Re: Binary transfer not working

Alex,

You are not doing anything wrong. Turns out forceBinaryTransfer doesn't
work because:

public void setPrepareThreshold(int newThreshold) throws SQLException {

checkClosed();

if (newThreshold < 0) {

forceBinaryTransfers = true;

newThreshold = 1;

}

else

*forceBinaryTransfers = false*;

this.m_prepareThreshold = newThreshold;

}

I'm trying to figure out if we should ever reset forceBinaryTransfers

I removed the line in italics above in the snapshot
https://oss.sonatype.org/content/repositories/snapshots/org/postgresql/postgresql/9.4-1201-jdbc41-SNAPSHOT/

Let me know if that works
